LIQUID-RAISING APPARATUS.

To all 'whom t may concern Be it known that l, J AMES F. REDDY, of Rochester, in the county of Monroe and State of New York, have invented certain new'and useful Improvements in Liquidv Raising Apparatus; and l do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.y and to the reference-numerals marked thereon.

The present invention which relates to liquid raising apparatus of the type in which compressed air is employed as the elevating medium, has for an object to provide a construction by which a strong. regulatable flow of liquid maybe obtained from driven wells.

Another object is to provide for the cleaning of the apparatus by agitating the body of liquid to be raised.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the cud of the specification.

In the drawings lwherein l have shown one embodiment of my invention: Figure 1 represents a view in side elevation: Fig. 2 a sectional view of the'upper portion of the same: Fig. 3 a sectional view of lower portions: Figs. 4, 5 and 6 each represent sections on line a-a and line b-b of Fig. 2, and show the three positions of both valves; and Fig. 7 represents a detail vicw of the upper portion of the apparatus illustrating the connection with the air supply.

One of the features of this invention is the provision in the air supply pipe of one or more adjustable nozzles,.by which the discharge of the air can be regulated and in this manner the flow varied, and another .feature is the provision of means for connecting the air supply to the discharge tube and tothe well casing whereby a ,surging of the liquid to be elevatedimay be effected,` this causing the cleansinglof the apparatus.

A well casing 1 of any suitable formis driven in the usual rmanner through the earth toV a stratum of stone or other hard,

substance which does not require to be supported against caving in; and arranged within the well casing and extending below the same is the liquid discharge tube 2 preferably having a perforated base or strainer Specification of Letters Patent.

3 at its lower end secured thereto by screw threads or other means.

Connected to the upper end of the well casing and of the discharge tube is a head which is divided into two chambers 4 and 5, the chambers being formed by contracting the head at G and the chamber 4l having a discharge 7. Suitable means, such as screw threads 8 at its lower end, serve to secure the well casing to the head: while suitable means such as screw threads 9 on the inner wall at the reduced or contracted portion Serve to secure the discharge tube and per mit the latter to communicate with discharge 7.

The perforated base or strainer may bc cleansed by means of devices for effecting a surging of the liquid within the casing. These devices consist in the present instance, of two connections 10 and 11, leading from an air supply 19r and having valves 13 and 14 arranged therein. These valves are of the twoway rotary type, that is, in addition to the usual inlet and discharge they have a discharge 15 leading to the atmosphere. The plug of the upper valve has one port 16 while that of the lower valve has ports 16 and 1Gb. The relation of the valves to each other is fixed and is such that when the well casing communicates with the atmosphere the discharge tube communicates with the air supply and vice versa, and when one is entirely closed the other will be entirely closed. For instance as shown in Fig. t when the port 16a in the valve 14- communicates with the air supply the port of valve 13 will connect the discharge with the atmosphere, when the port of valve 13 communicates with the air supply, as shown in Fig.` 5, the port 161 of valve 14 will cause. the well casing to communicate'with the at- Inosphere; and when both valves are en' supply pipe. v

The-raising or elevation of the llquid 1s well casing, rotary two way valves in said connections, and a shaft connected at each end to one of the valves.

6. The combination with a head formed with two chambers, one of which has a discharge, means for connecting a liquid discharge tube to one of said chambers, means for connecting a well casing to the other chamber, of an air supply, and means connecting the air supply to both chambers having discharges to the atmosphere and producing a surging action in the casing and in the liquid discharge tube.

7. The combination with a head formed with two chambers, one of which has a discharge, means for connecting a liquid dis charge tube to one of said chambers, and

` means for connecting a well casing to the other chamber. of an air supply, and means connecting the air supply to both chambers and producing a surging action in the casing and in the liquid discharge tube, embodying two connections, twoway valves in said connections, and means for simultaneously operating the valves to supply air alterlnately` to the casing and the discharge tu e.

8. The combination with a head formed with two chambers, one of which has a discharge, means for connecting a liquid discharge tube to said chamber, and means for connecting a well casing to the other chamber, of an air supply, connection between the yair supply and lthe liquid discharge chamber, connection between the air supply and the other chamber, and valves in said "connections having discharges to the atmosphere.

9. An air sup ly tube for liquid' raising apparatus provi ed with an air nozzle comprising a perforated cylindrical member having a surrounding seat at one endof the perforated portion and a member surrounding the erforated member guided on the exterior ace of the latter and having a seat movable toward and from the seat on the perforated member.

10. An air supply tube for liquid raising apparatus provided with an air nozzle comprising a perforated cylindrical member having a surrounding seat thereon, at one side of the perforated portion and a member surrounding the perforated member and having a seat co'iperating with the seat on said perforated member' and an internal annular shoulder' guided on the exterior face of the said perforated member.

11. An air supply tube for liquid raising apparatus provided with an air nozzle comprising a perforated cylindrical member having a surrounding seat thereon and a surrounding stop, and a member surrounding the perforated member and having a seat cooperating with theseat on said perforated member and an internal annular shoulder guided on the vexternal face of said perforated member and arranged to engage the stop on the latter.

12. An air supply pipe for liquid raising apparatus provided with an air nozzle comprising a perforated member having a surrounding seat at one end of the perforated portion and a surrounding stop at the other end of said perforated portion, and a perforated member having a seat to Coperate with the seat on said perforated member and an internal flange to cooperate with the surroundinfY stop.

13. An air supply pipe fbr liquid raising apparatus provided with an air nozzle comprising a perforated member having a surrounding seat at one end and a surrounding shoulder and a projecting guide at. the other end, and a member surrounding the perforated 'member and having a seat cooperating with the seat of the perforated member, an internal iange to coperate with the shoulder and a portion in which the projecting guide works.
